Astronomers used NASA’s James Webb Space Telescope to image the warm dust around a nearby young star, Fomalhaut, in order to study the first asteroid belt ever seen outside of our solar system in infrared light. But to their surprise, the dusty structures are much more complex than the asteroid and Kuiper dust belts of our solar system. Overall, there are three nested belts extending out to 14…
Re-analysis of data from NASA’s Voyager spacecraft, along with new computer modeling, has led NASA scientists to conclude that four of Uranus’ largest moons likely contain an ocean layer between their cores and icy crusts. Their study is the first to detail the evolution…
NASA has taken to the seas and skies to study the unique environment at the ocean’s surface, where marine ecosystems intersect with our planet’s complex atmosphere. On April 7, scientists participating in the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) embarked on…
While NASA retired its InSight Mars lander in December, the trove of data from its seismometer will be pored over for decades to come. By looking at seismic waves the instrument detected from a pair of temblors in 2021, scientists have been able to deduce that Mars’ liquid iron core is smaller and denser than previously thought.
The findings, which mark the first direct observations ever made of…
Where are flood waters flowing after major storms? Where are the changes in tree and plant cover after droughts, wildfires, deforestation, or mining? How much did the land move during an earthquake or volcanic eruption? Scientists routinely rely on data-intensive analysis…
NASA has selected 10 researchers from institutions across the U.S. to join the Science Working Team of the Japan Aerospace Exploration Agency’s Martian Moons eXploration (MMX) mission as NASA-supported participating scientists.
JAXA’s MMX mission, planned to launch in…
Icy Moonquakes: Surface Shaking Could Trigger Landslides
April 14, 2023
Many of the ice-encrusted moons orbiting the giant planets in the far reaches of our solar system are known to be geologically active. Jupiter and Saturn have such strong gravity that they stretch and pull the bodies orbiting them, causing moonquakes that can crack the moons’ crusts and surfaces. New research shows for the first time how these quakes may trigger landslides that lead to…
NASA’s Ingenuity Mars Helicopter Completes 50th Flight
April 14, 2023
NASA’s Ingenuity Mars Helicopter has completed its 50th flight on Mars. The first aircraft on another world reached the half-century mark on April 13, traveling over 1,057.09 feet (322.2 meters) in 145.7 seconds. The helicopter also achieved a new altitude record of 59…
NASA to Convene Mars Sample Return Review
April 14, 2023
NASA will convene a Mars Sample Return (MSR) Program independent review board, or IRB, to perform a review of current plans and goals for one of the most difficult missions humanity has ever undertaken: bringing samples from another planet to study on Earth.
Later this year…
Years in the making, a major software update that has been installed on NASA’s Curiosity rover will enable the Mars robot to drive faster and reduce wear and tear on its wheels. Those are just two of about 180 changes implemented during the update, which required the team to put Curiosity’s science and imaging operations on hold between April 3 and April 7.
“The flight software is essential…
